Abstract

BACKGROUND Kidneys are vital organs for excretory and many other biochemical functions in the human body. Most chronic diseases end up damaging the kidneys, acute to chronic, based on the cause and duration. Chronic kidney disease is a sequence of damages to the renal cells and parenchyma leading to progressive deterioration of kidney function, which eventually develops into terminal stage of chronic kidney failure. Chronic renal failure leads to a pro-oxidant state, which leads to damage to the renal cells and parenchyma and the amount of intracellular oxidative stress or extracellular oxidative stress has a relation to the severity of renal failure either directly or indirectly. The study aimed to find the correlation between high sensitivity c-reactive protein (hs-CRP) to lipid peroxidation product, malondialdehyde (MDA). METHODS This prospective study was designed and conducted from January 2018 to December 2019 in the Department of Biochemistry, Government Medical College, Ananthapuramu. The study comprised a total of 70 subjects in the age group of 35 - 65 years. The subjects of the approved study plan were divided into two groups; 35 subjects were healthy controls (group-1), and 35 subjects were chronic renal failure (CRF) patients. A blood sample was collected in Government General Hospital, Anantapuramu. RESULTS The sample was analysed for estimation of blood urea, plasma glucose, serum creatinine, Malondialdehyde (MDA) and C-reactive protein (CRP). The mean value of blood urea, serum creatinine, serum hs-CRP, serum MDA was higher in CRF (group-2) patients when compared to healthy controls (group-1) (p < 0.0001). We observed a positive correlation between serum MDA and serum creatinine (r = 0.46832), hs-CRP (r = 0.0234). CONCLUSIONS In CRF, oxidative stress is obviously evident, but the inflammation induced oxidative stress which can be corrected if detected early will reduce oxidative damage. Our study shows that there is an elevation in hs-CRP and MDA which confirms the presence of oxidative damage, inflammation and probably inflammation induced oxidative damage.
